 A Study on Motivation and Behavior of Recreational SCUBA Diver - The Case study in Long-Dong Bay, Northeastern Taiwan

研究生羅力 Li Lo

隨著台灣社會的發展,民眾越來越重視休閒生活,其中休閒潛水人口的增加,使人為接觸海底環境之頻率遞增,因此本研究旨在探討潛水者特性、潛水動機與水下行為間的相互關係,提供管理者與經營者參考。本研究在200971日~2010630日期間以北台灣東北角潛水活動較為密集的龍洞灣海域進行調查,經由潛水業者問卷調查結果顯示,此一年期間約有20,299人在此地潛水。由潛水動機問卷調查346份顯示,有65.3%的人是利用假日前來,其中以北北基(75%)且大專以上程度(87%)人數最多;以潛水者特性來看在樣區的女性潛水者為少數(32%),且女性在學歷、有導潛、收費區潛水等和男性潛水者有顯著差異;以潛水者動機來看,前六名依序為:和好朋友潛水、增加不同的生活體驗、沉浸在清涼的海水、天候的適宜、認識新朋友與訓練潛水技巧等,多為交友、天候及訓練為主要考慮因素。
 水下潛水行為調查88人發現,觸碰行為是會持續發生的,以擾動砂石(3.45/人)為最多,定點停留(2.84/人)次之,手主動觸碰(2.79/人)第三;以潛水者擾動砂石總次數的水下行為來看,初級潛水者、體驗潛水者、潛水歷史次數在40次以內的潛水者為多數。此外,實施潛水前簡報後,珊瑚磨損總次數明顯減少,在有導潛的干預下,手主動觸碰總次數、定點拍攝總次數及定點停留總次數等行為皆有顯著減少。
 綜合上述結果,本研究建議第一、規劃提供浮潛、潛水旅客進入珊瑚礁區的步道,改善環境設施增加便利性與安全性,應可以提昇女性潛水的意願;第二、以訓練和觀光性質劃分潛水區域、用潛水資格區分收費標準;第三、強化潛水前簡報與導潛干預功能,可以減少對海洋環境的衝擊。

 Abstract
 With the development of Taiwan’s society, people pay more attention to their leisure time. The increasing population of scuba diving increase the interaction between humans and the marine environment. Therefore, to investigate the characteristics, the motivations and the behavior under the sea of recreational divers are essential for managers and operators. This study deployed from July 1 2009 to June 30 2010 at LongDong Bay, the northeastern Taiwan where scuba diving activities are most common. With the preliminary survey, the estimated annual divers were 20,299 in this area. According to the questionnaires investigation of divers (n=346 persons), it showed 66.1% divers came on holidays. Among them, most people are from Taipei City, Taipei County, and Keelung City (75%). Most of than (87%) are, with or higher college degree (87%). Regarding the characteristics of the divers, female divers are less (32%) and have significant differences from male divers in education, with dive masters and the preferred pay area. As for the motivations marked by the divers, the top six factors are as follows: (1) the joy to dive with friends; (2) the increase of the different life experiences; (3) the pleasure to immerse in the sea water; (4) the amiable weather; (5) the chance to meet new friends and (6) the training of the technique of scuba diving. Most people considered making friends, weather and training are major attractions.

Regarding from the under the sea behavior investigation of the divers (n=88 persons), the touching activities occurred continuously, and most of them were disturbing the gravel (3.45 time/per person); the second one is the remained in one point (2.84 time/per person); the third one is touching by hands (2.79 time/per person).For disturbing gravel, the primary divers, discover, and those diving less than 40 times divers have higher times. In addition, diving briefing have significant differences in decreasing the friction of corals. When dive masters interfered the divers, the touch by hands, fixed photo taking and the time for remained in one point have significantly decreased.
 Summarize from these results, this resesrch suggests that: (1) to construct coral reel trails for divers and improve basic facilities to encourage females’ willingness to scuba diving; (2) separate scuba diving areas to different areas, such as training areas and tourism areas and charge in accordance with the qualifications of scuba diving; (3) enhance the briefing before scuba diving and the interfering of the dive masters. These activities would be useful to decrease the impact of divers on the marine environment.

2010 台灣太平洋延繩釣漁業海鳥混獲之分析

Analysis of seabird bycatch of Taiwanese longline in the Pacific Ocean.
研究生:               陳翊蓁 Yi-Jen Chen
近年來漁業行為對海洋生物多樣性的影響,已引起諸多關切。延繩釣漁船於佈餌時,海鳥會伺機衝向魚餌搶食而被魚鉤鉤到,造成海鳥傷亡而影響其生物資源量。本研究針對太平洋台灣鲔延繩釣漁業對海鳥的影響進行評估,分析2004 2008 年太平洋台灣鮪延繩釣漁船之觀察員資料,由觀察員紀錄之漁業作業項目中,與海鳥可能相關之變項,以相關檢定辨別變數間無共線性存在,再利用逐步迴(stepwise)程序選取模型的最佳組合,以此做為模型分析之候選參數,以泛線性模式 (Generalized linear model, GLM) 及泛加法模式 (Generalized additive model, GAM) 檢視延繩釣漁船對海鳥混獲之影響並透過Akaike information criterion (AIC) 之統計值篩選模型之最適模式。觀察員資料總計有56 航次,總觀察天數為3,973 天,總鉤數為10,192 千鉤,海鳥總混獲隻數為380隻,海鳥總目擊隻數為11,113 隻,海鳥混獲率 (bycatch per unit effort, BPUE) 最大值每千鉤為2.49 隻,最小值每千鉤為隻。以Poisson 估計之BPUE 均值每千鉤為0.037395 % 信賴區間每千鉤為[0.0336,0.0412]。影響模型顯著性的變數分別為年、餌料狀態與裝置避鳥繩。最終模式解釋變異GAM 小於GLM,顯示GAM GLM 對於解釋海鳥混獲之影響變因更適合。海鳥混獲易發生於未裝置避鳥繩、使用冷凍餌料及目擊隻數高者,因此,本研究建議漁船於高緯區作業的延繩釣漁船應使用解凍餌料、裝置避鳥繩等措施,以減少海鳥混獲之發生。
The impacts of fishing practices on marine biodiversity have drawn attention in recent years. The seabirds can be incidental caught while contending the baits with fishes, and this has caused the decreasing of some seabird populations. Observer data from 2004 to 2008 are used to analyze the interaction between seabirds and Taiwanese longline fisheries in the Pacific Ocean. We chose those possible related variables based on previous research to identify colinearity between factors by correlation analysis test. We also use stepwise regression to choose the best parameters for the model. Applying generalized linear Models(GLM) and generalized additive models (GAM) to find the influencing factors, we then selected the fitted model by Akaike information criterion(AIC). Among those 56 trips with 3,973 observation sets, 10,192 thousand hooks, three hundred and eighty seabirds are bycatch and 11,113 sighted seabirds. The seabirds bycatch rates is varied ranged from
0 to 2.49 per thousand hooks, and the estimated average was 0.0373 per thousand hooks (with 95 % confidence interval = 0.0336/1000 - 0.0412/1000). The significant factors included year, baits condition, tori lines and the number of seabird sighted. The final GAM model is better than GLM because of smaller explained deviance. Seabirds bycatch rates were higher in high latitude, without tori line and using freeze baits during fishing practice. We suggest longline vessels operating in high latitude should use thawed baits and set tori line to reduce seabirds bycatch.

一望無際的沙灘


文章日期:2010-07-28 11:37
周末,到Victoria Island 去探望多年老友
有幸跟著他們到海邊去露營~~~~Rathtrevor,Parksiville, BC
看到了"一望無際"的沙灘
抵達的時候,遙望滿天彩霞,靜謐的海水以及初昇的明月,
幾隻偶爾飛過的海鳥,彷彿由畫中浮現的美景。

[手邊沒有好的拼圖軟體,只好勉強接接圖,跟真實景況差的遠,只能說是釋義圖!]
次日清晨,再度造訪海邊時
海水已經退去,見到的是綿延長達二公里、延伸數百公尺遠的平坦沙灘地
淺淺的水塘,擠滿各種小螃蟹、貝類,挖洞、噴水,展現了無限的生命力
這應該是上潮間帶生物觀察課最好的地點了
待潮水漲起,水深亦不及膝,許多家庭老老小小在沙灘上嬉戲
一點沒有安全的顧慮,充其量小心跌倒給傷到了。

放心嬉戲的度假人們

沙地上練合氣道的小朋友

心裡想著
不曾在台灣見過這樣安全豐富的海岸呢!
轉念一想
我們的西南海岸、外傘頂洲,是否也可能是這般模樣呢?
只是,為著"發展"之名,多少年來以建設重工業為目標
迄今未變,似乎重工業才是唯一能夠讓民眾豐衣足食的方法
就看不見可能造成的汙染、資源的短缺、環境的破壞以及難以回復性~~~~
也許,很久很久以後,如果台灣真的能夠進步,真的能夠想開
也許可以像這個"維多利亞小鎮"
用露營車、運動器材用品、觀光業,來兼顧民眾的經濟問題、健康問題,以及環境的永續~~~~
one day~~~

附上GOOGLE地圖,就可以稍微估算沙灘地可以有多大了!
至少比整個露營地都來的大多了!

What's "visiting scholar? "


文章日期:2010-07-21 12:22
今天下午,到ISO, International scholar office 報到
本來以為只有三個月,很單純的用原來的B1簽證就好,
只是因為要到學校做研究,所以被要求另外申請J1簽證
過程就變得很複雜,先要提供各項詳細資料
之後會有一張DS-2019表格透過國際快遞從UW送到家
然後上網去繳錢,登記申請簽證
不光是繳四千多元簽證費
還要另要繳US$180的SEVIS費用
做啥用呢?今天就知道了
用來建立列管資料庫,從頭到尾追蹤,可能從一開始的身家調查,到後面建立動態資料庫,
所以,對於這個"國際學人辦公室"的運作,應該我們也盡了一些力吧!
負責人也很盡責的一一介紹文件上的欄位以及在校期間的規範
有一點是,除了去加拿大跟墨西哥短期進出OK外,去其他地方如果長一點的時間
應該要先報備,不然J1簽證可能會失效或者回不來
特別有帶眷屬的,就不要再亂跑出去。
...................
當然,很有意思的是,he said,
當年,美國認為這些訪問學者其實扮演了"AMBASSDOR"的角色
不管是把他的本國文化帶到美國校園
或者把美國校園文化帶回當地國,
都是價值不菲的文化學術交流
所以才特別建立這種簽證制度,
當然,最後也不忘提醒
專心研究,有空的時候
Don't forget to have fun!
You are not only ambassdor,
but also advanture here!

烤饅頭與藍莓醬


文章日期:2010-07-19 13:03
當資源有限的時候
就會開始思考變通的方法
舉例來說
想吃饅頭,但是沒有蒸籠,
卻有個超大的烤箱,
於是,變成烤饅頭!
路邊隨手摘來的藍莓
就變成藍莓醬了!
當然,這藍莓的來源
也要感謝此地的識途老馬了。

WOW Julia
Buleberry 是一百分食物呢,台灣不容易買到 即便買到也都不是頂新鮮的,你竟然可以隨手捻來!
好好享受你的生活喔! 最近經歷搬家後,發現古人說的,無入而不自得,端看個人造化。
讓我們一起好好享受每一個當下~

Seattle, I am back!


文章日期:2010-07-18 05:33
Went to Seattle many years ago,
though only two weeks,
but I love city,
sunshine, green and beautiful gardens, blue blue sky and lakes,
very attractive zoo and aquarium,
famous UW and many experts here,

after many year, when I have a chance to study in US again
I think,
I have to come back to this beautiful city, in the beautiful season!

So, here I am, another two months in Seattle!

台灣的海洋公民科學

 海洋公民科學 提到台灣的生態公民科學,許多人首先會想到路殺社,或是龐大的觀鳥社群。然而,相較於陸地的易接近性,海洋領域的公民科學充滿了挑戰。在這片廣袤的藍色世界中,規模最大的公民科學行動或許是由Ocean Conservancy發起的國際淨灘倡議(International C...
